Joseph Kosinski, who directed Legacy, is attached to helm this installment, which is being developed with a renewed purpose under Alan Horn, who took the reins of Disney Studios in June.

Some considered the dark and trippy Legacy -- which teamed newcomer Garrett Hedlund with Jeff Bridges, star of the 1982 original Tron -- a lukewarm performer when it opened in December 2010. But the film grossed $400 million worldwide, good enough to spark interest in prolonging the franchise. With that foundation and a strong brand, Disney believes it can really go for broke with a new movie.

Plot details are being kept under wraps. David DiGilio wrote an earlier draft of the script. Justin Springer, a co-producer on Legacy, is producing Tron 3.

Wigutow already is working with Disney on the adaptation of Peter and the Starcatchers and worked on Parallel, another Disney project being produced by Springer. Wigutow also wrote Eragon and worked on Relativity’s remake of The Crow and Summit's remake of The Osterman Weekend.

He is repped by UTA, Tobin Babst at Kaplan/Perrone Entertainment and Sloane Offer.
